TO ALL WHOM IT MAY CONCERN:

Be it known that I, JAY DENSMORE, of Holley, in the county of Orleans, and State of New York, have invented a new and useful Rotating-Tooth Cultivator; and I do hereby declare that the following is a full, clear, und exact description of the construction and operation of the same, reference beinghad to the annexed draw. ings, making a part of this specification, in which- Figure 1 is a perspective view, and

Figure 2 a longitudinal section of the tooth and standard.

I construct my cultivator of the frame B, mounted upon the wheelsA A, by means ofthe cranks Fattaehed to the ends of the shaft G, the crank-pins w being the arms upon which the wheels revolve. To the shaft G is attached the lever L, by means of which the frameB is raised or lowered, and is held in position at any desired point by means of the pin 3 inserted in any one of the holesI 4 4 4 4 4 4 4 in the cross-bar N. The draughtpole M is attached to the frame B by means of the guides K and I. The forward end of the frame B is raised or lowered by raising or lowering the pin t in the guide I. The drivers seat C is attached by means of thc spring E. The teeth are constructed ofthe hub c, to which are bolted the wings or teeth a a a a, or their equivalents, more or less. The pin P is held securely in the hub by the key n, and revolves in the bush o in the journal in the bottom of thc standard S, the bush o and pin P being both held in place by the Washer z'and key Z. The teeth are secured to the frameB by the belts 6 6 6 6, at an angle to the draught of fortylve degrees,

more or less, as may be desired.

The teeth in the back row are set so as to counteract the side draught of the teeth in the forward row, or vice versa, as shown in Iig. 1. When the teeth are let down upon the ground, and drawn over it, tho shape of the wings or teeth a aa a causes them to enter to any desired depth, and their revolving causes the earth to be very thoroughly stirred and pulverized. The spaces between the wings or teeth a a a aprevent the wet earth from l'illing up and clogging the centres of the teeth. When the pin l? and bush o become worn, they can be renewed at a. slight expense and trouble. Y A

What I claim as my invention, and desire to secure by Letters Patent, is-

1. A rotating cultivator-tooth, consisting of any number of teeth, attached to a hub or common centre, around-which they arc free to revolve, and set at an angle to the draught, substantially asbdcscribed.

2*. The combination and arrangement, with a rotating cultivator-tooth, of the standards, the pin P, the bush o, the washer z', and the keys Zand n, substantially as set forth and described.

y3. The combination and arrangement, with a rotatingt-ooth cultivator, ofthe frame B, the shaft G, the cranks F, the wheels A A, the lever L, the pin 3, the cross-bar N, and the holes 4 4 4 44 4 4, substantially as set forth and described.

4.. The combination and arrangement, with a rotating tooth-cultivator, of the pole M, the guides K and I, v

the pin t, the holes 2 2 2 2 2 2, the drivers seat C, and the spring E, substantially as set forth and described.
